SIT1042AQT是芯力特(SIT)推出的高可靠性CAN-FD总线收发器,专为需要高速数据传输与宽温环境的工业、汽车及新能源领域设计。相比传统CAN收发器,其核心价值在于兼容CAN-FD协议并支持5Mbps高速传输,同时具备-40℃至+150℃的宽温能力,可直接替代传统CAN收发器实现总线速率升级,无需大幅改动硬件设计。
SIT1042AQT支持CAN-FD协议(CAN Flexible Data-Rate),最大数据速率可达5Mbps(是传统CAN的5倍),可在不改变原有CAN总线拓扑的前提下,实现大数据量的实时传输(如工业多传感器阵列、汽车BMS的多电池数据)。同时向下兼容ISO 11898-2标准CAN协议,与传统CAN节点可无缝通信。
采用SOP-8标准贴片封装,引脚布局与主流CAN收发器(如TJA1050)一致,可直接替换传统CAN收发器实现CAN-FD升级,降低客户硬件改版成本。引脚功能清晰(VCC、GND、CAN_H、CAN_L、TXD、RXD、STB、NC),便于焊接与调试。
内置基础总线防护电路(过流保护、静电防护),可承受±8kV接触放电、±15kV空气放电的ESD冲击,适配工业现场电磁干扰环境(如电机、变频器附近);CAN_H/CAN_L差分总线具备共模抑制能力,抗干扰性强。
工作电流典型值<10mA,支持待机模式(待机电流<1μA),适合电池供电的便携设备或低功耗系统(如新能源充电桩待机监控)。
采用芯力特自主半导体工艺,通过AEC-Q100(汽车级)或工业级可靠性测试(高低温循环、湿热老化),平均无故障时间(MTBF)超100万小时,满足长期稳定运行需求。
SIT1042AQT的性能特点使其适用于多领域高速CAN-FD通信:
SIT1042AQT作为芯力特CAN-FD收发器核心产品,以5Mbps高速率、-40~150℃宽温、SOP-8封装兼容性为核心优势,解决了传统CAN总线速率不足的痛点,兼顾恶劣环境可靠性。其低成本、易替换的特点,适合客户从传统CAN向CAN-FD升级的需求,广泛覆盖工业、汽车、新能源等多领域应用。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
